Specification of Letters Patent.

Application filed July 27, 1914. Serial No. 853,374.

State of Illinois, have invented certain new i and useful Improvements in Cultivators, of

the following is a specification, reference being had to the accompanying drawings. 1

My invention relates to certain new and useful Improvements in Cultivators, and V has for its object to provide an attachment which while the cultivator is in operation will protect the shovel carrying supports of the machine from which would otherwisetend to envelop the same.

iVith this end in view my invention consists in the construction and arrangement hereinafter more fully described.

Inv order that those skilled intheart to which my invention appertains may know how to make my attachment and apply the same to a cultivator and fully appreciate the operation and advantages of the same, I will now describe the construction and manner of attachment referring bv numerals to the accompanying drawings in which- Flgure 1 1s a side elevation of an ordinary cultivator equipped with my improved attachment; Fig. 2 is a detail rear elevation on enlarged scale of the left hand shovel carrying supports with the vertical chain omitted; Fig. 3 is a horizontal section on enlarged scale taken on the line aa of Fig. 2; Fig. 4 is a detail cross section on the line bb of Fig. 2; and Fig. 5 is a detail plan view on enlarged scale of the main idler sprocket and support.

Similar reference numerals indicate like parts in the several figures of the drawings, but to avoid prolixity of description and confusion in reference numerals, only such parts of an ordinary cultivator as may be necessary in showing the relation therewith of my improvements are described.

1 are the shovel supports mounted in the usual yielding and adjustable frame 2 and arranged around the supports and extendweeds and rubbish 7 that suflicient 7 is a post mounted upon the frame 2, and formed at the upper end with a horizontal arm 8, carrying a sprocket gear 9, and a bevel gear 10, which latter meshes with a similar bevel gear 11 at the upperend ofa Patented J an. 12, 1915.

vertical shaft 12, rotatable within a vertical post 13, mounted on the frame 2. This shaft carries at its lower ,endthe sprocket pinion 6, heretofore referred to, and which causes the chain 5 to travel around and rotate the gears 4 and consequently also the sleeves 3. The bevel gear 11 is mounted upon the upper end of the post 13, on ball bearings (not shown) and not necessary to describe.

From the description thus far given it will be seen that when thevertical shaft 12, with its sprocket pinion 6, is rotated the sleeves 3 will necessarily be; rotated, and as they are formed at their lower extremity with radial teeth orarms 14, (see Fig. 4), it will be seen that the sweep of said teeth will gather and deflect any rubbish", and weeds away from the shovelsupports.

I will now describe the means employed for transmitting motion to the sprocket gear 9 andbevel gear 10.

The hub of the wheel is provided with a sprocket gear 15, and mounted upon the main frame 16, of the machine is a transverse shaft 17, having fixed thereto a sprocket pinion 18, and sprocket gear 19. A sprocket chain 20, traversing the hub sprocket 15, and pinion 18, necessarily rotates the shaft 17, with its gear 19. Secured to the frame 2 in any suitable manner is a gear supporting frame 21, within the parallel vertical sides of which are journaled three idler sprockets 22, 23, and 24. A sprocket chain 25, traversing the driven gear 19, idler 24, the gear 9, necessarily transmits motion as heretoforestated to the vertical shaft 12, and causes the sleeves 3 to be rotated around the shovel supports.

idler 23 and sprocket By reference to Fig. 1, it will be seen I slack is provided in the sprocket chain '25 to permit of any vertical yielding, or adjustment of the frame 2, and shovel supports which is provided for by a coil spring 26, attachedin anobvious manner at one end to the frame 2, and at the other to a hand lever 27 I have for the sake of brevity, described the construction and arrangement for ac complishing the purpose of my invention j surrounding said their lower extremities with radial arms or at one side only of the cultivator, but it will be understood that the arrangement may be duplicated at the other side, and if desired and instead of transmitting motion from the wheel hub at such side, it may be taken as heretofore described from the shaft 17, extended suitably for the purpose.

, Having described the construction and operation as well as the purposes of my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a cultivator, in combination with the shovel supports or legs, rotatable sleeves supports and provided at teeth, and means intermediate the cultivator wheel and the sleeves for rotatng the sleeves substantially as and for the purpose set forth.

2. In a cultivator provided with rotatable sleeves surrounding the shovel supports, and having radial arms or teeth at the lower extremities and sprocket gears at their upper extremity, a sprocket chain traversing said gears, a chain driving sprocket pinion mounted upon a vertical shaft provided at its upper end wth a bevel gear, and means intermediate said bevel gear and the wheel hub of the machine for driving the said bevel gear substantially as and for the purpose set forth.

. 3. In a cultivator provided with rotatable sleeves surrounding the shovel supports and provided at their lower extremities with radial arms or teeth, and with sprocket gears Gopies of this patent may be obtained for five cents each, by addressing the at their upper ends, a vertical shaft provided with a sprocket pinion at its lower extremity and a bevel gear at its upper end; a sprocket chain traversing the said sprocket gears and pinion; a bevel gear meshing with the bevel gear of the vertical post; a sprocket gear connected with said bevel gear, and means intermediate said sprocket gear and the hub of the cultivator wheel for driving the sprocket gear substantially as set forth.

I. In a cultivator embracing rotatable sleeves surrounding the shovel supports and equipped with radial arms or teeth for gathering and sweeping away weeds and rubbish, and means such as described for trans mitting rotative motion to said sleeves; a sprocket gear upon the hub of the cultivator wheel, a sprocket pinion and sprocket gear secured upon a transverse shaft journaled upon the cultivator frame, a sprocket chain traversing the hub sprocket and the pinion sprocket and a slack sprocket chain traversing the sprocket gear upon the transverse shaft and a sprocket gear upon the shaft for transmitting motion to the sleeve rotating devices, and idler sprockets intermediate the driving and driven sprocket gears substantially as hereinbefore set forth.

It testimony whereof I hereunto aiiix my signature in the presence of two witnesses.
